Loom.

SPECIFICATION forming part of Letters Patent No. 436,937, datedSeptember. 23, 1890.

' Application filed ram, 17, 1890. Serial No. 340,203. (No model.)

found that the doubled edges at opposite sides of the loom have atendency to draw in and thus narrow the fabric and draw the warpthreadsthereat out of proper alignment, and thereby vary the grade of thetexture of the said portions of the fabric from that of the central ormain portion thereof.

The object of this invention is to obviate the aforesaid defect; and tothat end the invention consists, essentially, in sustaining a bar orrule stationary in proximity to and parallel with the reed and Withinthe warp and fabric, as hereinafter more fully described, and set forthin the claim.

In the accompanying drawings, Figure 1 is a side elevation of a loomembodying our improvements. Fig. 2 is a plan view taken in the plane mas, Fig. 1. Fig. 3 is an enlarged vertical transverse section on theline y y, Fig. 2. Fig. 4 is an enlarged vertical longitudinal section online ,2 2, Fig. 2; and Fig. 5 is a detached side View of one of thetemples.

Similar letters of reference indicate corresponding parts.

A represents the loom-frame; B, the warpbeam, on which the warp iswound; C, the socalled whip-roll, over which the warp passes from theWarp-beam.

D denotes the cloth-beam, upon which the fabric is wound as it is woven;F, the harness r or heddles, and I the reed, which latter is carried onaswinging frame I, suspended from the top of the loom-frame. All of saidparts are arranged in the usual and well-known ward at said edges. Thesaid temples may be either of the form designated jaw-temples or of thecharacterof roller-temples, as shown in the drawings, or of any othersuitable and well-known form. The said temples are supported on arms I)12, secured to the loom-frame, and grip the folded edges of the endlessfabric near the line of Weaving. Between the reed I and templesaa, andparallel with the said reed, we place a small rod or rule 0, extendingacross the loom and lying within the two layers of fabric, and with theinner edge in close proximity to the line of weaving, the said rod orrule being of a length to reachcompletely across the interior of thetubular fabric and hold the same laterally distended immediately back ofthe temples, which grip the folds of the fabric and retain the samedistended. This rod or rule a we sustain stationary in its aforesaidposition, preferably by means of wires d 01, extending straight andparallel from the ends thereof through the reed I and harness F, andsecured to the whip-roll O or to some fixed portion of the loom-frame atthe rear end thereof. In passing the shuttle alternately through theupper and lower sets of warp the weft-thread passes around the exteriorof the wires (1' d, and consequently the outer Warp-threads are relievedof the inward strain of the weftthreads, and therefore the texture ofthe fabric is rendered uniform throughout.

We are aware that prior to our invention a board has been introducedinto the fabricfor the same purpose for which the rod or rule 0 isemployed; but such a board has been so arranged near the reed as tocause the latter to push the said board forward, and a spring or weighthas been employed to draw the board rearward during the operation of theloom. This forward-and-back moving board, however, frequently caughtwith its ends the threads of the fabric and thereby disarranged thesame, which defect is entirely obviated by the employment of thestationary rod or rule 0, as hereinbefore described.

To further insure evenness in the texture of the fabric we employconvenient means for throwing the tension from the warp-beam, whendesired, the said means consisting of a bell-crank e, pivoted to therear portion of the loom-frame and having one of its arms connected withthe tension -lever l, which bears on the warp-beam and has a spring fconnected to its free end, as shown in Fig. 1 of the drawings, the otherarm being connected by a rod 0" with a hand-lever h. By means of thesaid lever and its described connection with the tension-lever Z thefriction of the latter upon the Warp-beam can be moderated while theloom is in motion.

Having described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

The combination, with the loom-frame, swinging frame suspended from thetop of the loom-frame, reed carried on said frame,

and the harness, of the arms I) b, secured to the sides of said frame,temples a a, supported on said arms and gripping the folds of thefabric, the rod 0, lying within the fabric between the temples and reedand parallel with the latter, and wires d 01, extending from the ends ofsaid rod through the reed and harness and secured to the rear of the100m, substantially as described and shown.

.In testimony whereof we have hereunto signed our names this 8th day ofFebruary, 1890.
